It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
This pull request modifies the _VerticalTransitionPage class in a Flutter API example by removing several constructor parameters and hardcoding their values. Review feedback indicates that these parameters should be retained to preserve the flexibility of the example and adhere to the standard Page API contract. Additionally, the feedback suggests reordering class members to group constructor-initialized fields together for better logical structure.

These parameters should not be removed. This example is intended to demonstrate "flexible" route transitions, and removing the configuration parameters (such as maintainState, fullscreenDialog, key, name, and arguments) makes the _VerticalTransitionPage class significantly less flexible and less useful as a reference for developers. \n\nFurthermore, key is essential for proper route reconciliation in the Navigator. Even if these parameters are not currently exercised by the example's call sites, they should be retained to maintain the expected Page API contract and the intended flexibility of this example.
References
- Write what you need and no more, but when you write it, do it right. In this case, 'doing it right' involves maintaining the standard Page API contract for a class intended to be a flexible template. (link)

The class members should be ordered logically. It is generally preferred to group constructor-initialized fields together, followed by fields with hardcoded initializers. Currently, allowSnapshotting (a constructor parameter) is separated from child by the hardcoded maintainState and fullscreenDialog fields.

- Other class members should be ordered logically (e.g., by lifecycle, or grouping related fields and methods). (link)

The lint rule will start reporting these unused parameters. These are parameters for which no arguments are ever given, so they are dead code.
